ICD-10 Code F18.28 – Inhalant dependence with other inhalant-induced disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.28 – Inhalant dependence with other inhalant-induced disorders
What it is
Use this code for dependence on inhalants when the record also shows another inhalant-induced disorder. It identifies a substance use disorder involving inhaled chemicals, not a one-time exposure.
Clinical signs
Clinical features vary; refer to documentation. Records may describe compulsive inhalant use, tolerance, withdrawal, or continued use despite harm, along with another inhalant-induced condition.
When to use this code
Assign F18.28 when the provider documents inhalant dependence and a separate inhalant-induced disorder, such as mood, psychotic, or other specified effects. Use the code only when both elements are clearly supported in the note.
If the chart lists inhalant use without dependence, or the related disorder is not specified, check documentation before coding. The diagnosis should reflect the provider’s final assessment, not suspicion alone.
Do not use for
Do not use this code for simple inhalant abuse, accidental exposure, or poisoning without dependence. Do not apply it when no additional inhalant-induced disorder is documented.
Coding tip
Look for explicit provider wording that links dependence to another inhalant-induced disorder before assigning F18.28.
